Recently, a team of scientists announced that they have discovered the world's first room temperature superconducting material, LK-99. For a moment, the global scientific community was boiling. What is room temperature superconductivity and has it really been achieved? What impact will it bring to us? Perhaps a new 'industrial revolution' will begin from here on. What is room temperature superconductivity, and material acquisition is comparable to "alchemy"? Superconductivity refers to the phenomenon where the resistance of certain materials suddenly disappears and there is no resistance when current passes through. The currently discovered superconducting materials exhibit superconducting properties only in extremely special environments, such as high pressure, high temperature, or low temperature. The cost of maintaining this environment alone is very high, which is why the room temperature and atmospheric pressure superconductivity of LK-99 has sparked heated discussions. Screenshot of arXiv website paper. It started on July 22. Through two papers and videos, the relevant research team of the Korean Quantum Energy Research Center announced that under normal pressure, a modified lead Apatite crystal (LK-99) could behave as a superconductor below 400K (127 ℃). The above experiment began to be replicated globally for a while, as the synthesis of the material required a long time of heating, etc. This process has been mocked by many netizens as "furnace refining". Taking China as an example, according to incomplete statistics of public information, teams from Beihang University, Qufu Normal University, Huazhong University of Science and Technology and others conducted replication experiments. The video uploaded by the team of Huazhong University of Science and Technology on station B shows that the "superconducting material" is smaller than a toothpick and can be compared to a needle tip. The experimental results need to be observed under a microscope. Whether the magnet is of N or S grade, the material is repulsive. This video once became the highest ranked video on Bilibili's ranking. Screenshot of Station B. According to the above video introduction, under the guidance of Professor Chang Haixin, Wu Hao, a postdoctoral fellow and Yang Li, a doctoral student in the School of Materials of Huazhong University of Science and Technology, successfully verified and synthesized LK-99 crystal that can be magnetically suspended for the first time. The suspension angle of this crystal is larger than that of the sample obtained by Sukbae Lee (Korean scientist), and it is expected to achieve non-contact superconducting magnetic suspension in real sense. But what's interesting is that the results of "refining" superconducting materials seem to have a lot of randomness. For example, the research team of Beihang University said that LK-99 material was successfully prepared, and no maglev phenomenon and zero resistance phenomenon were observed. One of the six samples of Sun Yue's team from Southeast University observed a decrease in 110K resistance, but no complete Diamagnetism was measured. The experimenter speculated that the superconducting component in the sample was very low. Is it possible to achieve this, and what are the difficulties? Is it possible to achieve room temperature superconductivity? What are the difficulties? Why is it causing countless scientists to "bend over". On August 2nd, the Korean Superconducting Society announced the establishment of the "LK-99 Verification Committee" to verify the authenticity of the results. Up to now, the Society has announced that LK-99 cannot be called a Room-temperature superconductor according to the data provided in two papers and the released videos. Professor Xiao Chijie from the School of Physics at Peking University stated in an interview with China News Agency that room temperature and atmospheric pressure superconductivity is the holy grail in the field of physics and one of the human dreams. "Before violating the fundamental principles of physics and being confirmed as false, we need everyone to bring their dreams with us
